INTRODUCTION 


It  is  a  generally  recog- 
nized fact  that  less 
ground  grain  is  re- 
quired to  produce  a 
given  amount  of  milk, 
meat,  or  work,  than 
whole  or  unground 
grain.  The  average 
saving  in  whole  grain 
by  the  use  of  the  feed 
grinder,  has  been  plac- 
ed by  a  prominent  au- 
thority at  12'/^;  many 
single  instances  show- 
ing the  amount  saved 
to  be  as  high  as  35  7o- 


The  mission  of  the  feed 
grinder  is  to  so  prepare 
or  treat  the  grain  that 
its  full  nutritive  value 
can  be  wholly  utilized 
for  all  feeding  purposes 
on  the  farm.  A  trial  of 
the  machine  forcibly 
emphasizes  its  value. 
A  complete  descrip- 
tion, with  numerous  il- 
lustrations of  the  chief 
points  of  merit  of  the 
International  Feed 
Grinders  are  given  in 
the  following  pages.

The  International  Feed  Grinder 


International  feed  grinders  are  built  in  two  types,  B  and  C.  Type  B  is  designed 
especially  for  grinding  corn  on  the  cob.  This  style  of  mill  is  built  in  two  different  sizes— one 
with  8-inch  grinding  plates  and  a  larger  size  with  10-inch  grinding  plates.  Type  C  is  designed 
for  grinding  small  grain  only,  such  as  wheat,  barley,  oats,  shelled  corn,  etc.,  and  those  wishing 
a  high  speed  mill  that  will  grind  small  grain  very  rapidly  will  find  this  type  especially  efficient. 
This  type  of  mill  is  built  in  one  size  only  with  8-inch  grinding  plates. 

Capacity  of  International   Feed  Grinder 

The  capacity  of  the  International  feed  grinder  varies  according  to  the  condition  of  the 
grain,  fineness  to  which  the  grain  is  reduced,  the  speed  at  which  the  grinder  is  run,  and  the 
amount  of  power  used.  It  is  difficult  to  make  a  definite  statement  regarding  the  capacity  of 
the  grinder,  as  these  four  factors  vary  so  greatly.  The  following  table  indicates  the  capacity 
of  the  grinder  for  different  grains,  when  the  machine  is  operated  at  maximum  speed  with  a 
proportinate  horse  power  gasoline  engine,  and  the  grain  is  in  average  condition:

The  table  below  indicates  the  speed  of  the  International  feed  grinder  when  operated 
with  an  I  H  C  gasoline  engine  equipped  with  regular  pulley  from  4  to  20-horse  power.  In 
order  to  secure  the  greatest  capacity  with  these  grinders,  they  should  be  operated  at  maximum 
speed.  This  will  permit  feeding  the  grinder  to  its  fullest  capacity.  The  minimum  speed 
for  the  8  and  10-inch  grinders  is  300  revolutions  per  minute,  and  the  maximum  speed,  when 
the  fly  wheel  is  used,  is  600  revolutions  per  minute.  When  run  at  a  speed  above  600  revo- 
lutions the  fly  wheel  should  be  removed.

FEED 
GRINDER 


0l^^ 


This  grinder  has  sufficient  capacity  for  the  needs  of  the  average  farmer.  It  can  be 
driven  with  from  4  to  10-horse  power,  the  capacity  of  the  mill  being  determined  by  the  amount 
of  power  used,  the  speed  at  which  the  mill  is  run,  the  condition  of  the  corn,  and  the  fineness 
of  grinding.  This  style  of  mill  will  run  at  about  75  revolutions  per  minute  for  each  horse 
power,  and  do  satisfac- 
tory work,  but  to  secure 
the  best  results  the  mill 
should  attain  a  speed  of 
not  less  than  300  revo- 
lutions per  minute.  The 
speed  can  be  increased 
to  600  revolutions  with 
perfect  safety. 

When  grinding  dry 
corn  on  the  cob  with  a 
4-horse  power  engine, 
the  speed  should  be 
about  300  revolutions 
per  minute,  at  which 
speed  the  capacity  will 
be  from  ten  to  fifteen 
bushels  per  hour;  where- 
as, if  an  8-horse  power 
engine  were  used,  the 
speed  would  be  about 
600  revolutions  per  min- 
ute, and  from  30  to  36 
bushels  could  easily  be 
ground.  ,  .^__  ,  ^     ,

International   10-Inch  Feed  Grinder 


I; 


TYPE  B 

In  construction  the  10-inch  feed  grinder  is  very  similar  to  the  8-inch  grinder.  The 
frame  and  hopper,  however,  are  8  inches  longer  and  the  main  shaft  has  a  larger  diameter. 
This  grinder  has  proved  to  be  exceptionally  popular  with  dairymen,  stockmen,  and  feed-store 
men,  where  a  large  size  grinder  is  required.  Six  to  15-horse  power  may  be  used  to  operate  this 

grinder.  When  corn  is 
dry  and  in  good  condi- 
tion, this  grinder  run- 
ning at  a  speed  of  from 
33  to  40  revolutions  per 
minute,  for  each  horse 
power,  will  grind  from 
13  to  60  bushels  of  ear 
corn  per  hour. 

In  breaking  and  grind- 
ing corn  on  the  cob,  330 
to  300  revolutions  per 
minute  generally  gives 
the  best  results.  When 
a  larger  engine  is  used 
this  feed  grinder  can  be 
run  up  to  700  revolu- 
tions per  minute.  As  a 
precaution,  however,  the 
fly  wheel  should  be 
taken  off  whenever  the 
speed  goes  over  600  revo- 
lutions per  minute.

Large  Steel  Hopper 


The  hopper  is  exceptionally  large  and  is  made  of  sheet  steel.  The  inside  of  the  hopper 
is  perfectly  smooth.  There  are  no  projections  to  obstruct  the  grain.  It  is  reinforced  at  the 
top  to  prevent  it  from  being  bent  out  of  shape.

Breakers 

The  breakers  which  mash  up  the  cobs  and  also  act  as  a  force  feed  in  working  the  grain 
toward  the  grinding  plates,  are  all  located  on  the  steel  shaft  as  is  shown  in  the  illustrations 
below.  The  points  of  these  breakers  are  chilled  which  insures  lasting  qualities.  The  chilled 
concave  is  placed  just  below  the  breakers,  being  fastened  to  both  sides  of  the  frame  with 
wooden  pins.  This  construction  ehminates  the  possibiUty  of  springing  the  main  shaft  and 
breaking  the  grinder  should  a  stone  or  a  piece  of  iron  get  into  the  hopper,  as  the  wooden  pins 
will  snap  before  the  grinder  is  damaged.  The  flow  of  grain  into  the  grinding  plates  is  regulated

by  means  of  a  shut-off 
which  is  operated  by  a 
small  lever  just  above 
the  grinding   plates. 
This  shut-off  leaves  nothing  to  wish 
for  as  not  a  particle  of  grain  is  admit- 
ted into  the  grinding  plates  when  it 
is  closed.

Spring   Tension 


The  grinding  plates  are  held  in  position  by  a  heavy  spring  which 
minimizes  the  danger  of  breakage  of  the  plates  should  a  hard  foreign  sub- 
stance get  into  the  grain.  The  grinding  plates  are  held  apart  by  a  shoulder 
on  the  tension  rod  which  prevents  the  spring  from  forcing  them  together 
when  there  is  no  grain  in  the  mill.  Breakage  is  further  guarded  against 
by  a  very  convenient  lever  located  at  the  end  of  the  shaft.  By  means  of 
this  lever,  it  is  possible  to  separate  the  plates  without  changing  the  ad- 
justment. 

Grinder  Parts 

The  crushing  and  grinding  parts  of  the  International  feed  grinder  are 
driven  by  the  heavy  steel  shaft  which  extends  through  the  grinder.  This 
shaft  runs  in  extra  long  anti-friction  Babbitt  bearings.  The  stationary  grind- 
ing plate  is  bolted  to  the  frame  of  the  mill,  while  the  running  plate  is  attach- 
ed to  the  shaft,  and  is  self-aligning.  This  self-alignment  is  secured  by  means 
of  a  ball-and-socket  connection  which  permits  the  running  plate  to  align 
itself  at  all  times  to  the  one  on  the  frame.  This  construction,  among  other 
great  advantages,  insures  an  even  running  mill  and  evenly  ground  feed. 
The  cross  section  illustration  on  this  page  shows  the  construction  of  the 
ball-and-socket  connection. 

The  end  thrust  of  the  shaft  is  taken  up  by  a  ball  bearing. 


Grinding 
Plates 

This  type  grinder  is 
regularly  equipped  with 
one  pair  of  medium 
grinding  plates  and  one 
pair  of  fine  grinding 
plates.  At  a  shght  ad- 
ditional cost,  one  pair 
of  coarse  or  extra  fine 
grinding  plates  can  be 
secured.

Sacking  Elevator  Attached  tO  the 
10-Inch  Feed  Grinder 


i 

i 


Sacking  Elevator 


The  chief  feature  of  this  elevator  is  a  divided  spout  to  which  two  sacks  can  be  attached 
at  the  same  time ;  while  one  sack  is  being  filled,  the  other  may  be  removed  and  another 
quickly  adjusted  in  its  place.  This  is  a  very  convenient  elevator  for  putting  ground  feed  into 
sacks.  It  is  well  made,  efficient,  and  can  be  attached  either  to  the  right  or  left  of  the  grinder. 
Both  sacking  and  wagon  elevators  can  be  readily  attached  to  the  Types  B,  8-inch  and 
10-inch  mill  or  Type  C.    The  wagon  elevator  is  shown  on  the  following  page. 

Extras 

A  large,  heavy  fly  wheel  is  furnished  with  the  International  feed  grinder  as  an  extra 
at  a  slight  additional  expense.  Special  breakers,  shown  on  page  5,  to  take  the  place  of  the 
regular  breaker,  will  also  be  furnished  at  a  nominal  cost.

Wagon  Elevator  Attachment 


Any  fariiier  who  uses  a  wagon  elevator  attachment  will  testify  as  to  its  time  and  labor- 
saving  properties.  When  ground  feed  is  to  be  placed  in  a  wagon,  or  bin,  this  elevator  delivers  it 
direct  without  handling.  It  is  made  of  well-seasoned  lumber  and  is  very  strongly  put  together. 
The  conveyor,  should  it  become  slack,  can  be  tightened  very  easily  by  means  of  adjustable 
tighteners  with  which  the  upper  shaft  is  provided. 


Wagon  Elevator   Attachment 

The  illustration  shows  the  elevator  equipped  with  a  wagon  spout  and  a  sacking  attachment 
which  are  interchangeable  on  this  elevator.  The  wagon  spout  works  on  a  swivel  and  can  be 
adjusted  to  deliver  the  ground  feed  in  any  desired  direction.  It  can  also  be  removed  very 
easily  when  the  sacking  attachment  is  to  be  used.  The  wagon  spout  is  shipped  regularly  with 
the  wagon  elevator.  If  a  sacking  attachment,  which  can  be  secured  at  a  slight  additional 
expense,  is  desired  in  place  of  the  wagon  spout,  it  should  be  so  stated  when  ordering.

International  8-inch  Small  Grain  Grinder 

TYPE  C 


Farmers  wishing  to  grind  small  grain,  such  as  wheat,  oats,  barley,  shelled  corn,  etc.,  will 
find  that  the  Type  C  small  grain  grinder  will  supply  this  want.     It  was  especially  designed 
to  grind  satisfactorily  all  such  small  grains.    It  is  built  along  the  same  lines  as  the  Inter- 
national Type  B  feed  grinder  described  on  the  preceding  pages,  with  the  exception  that  the 
arrangement  of  the  hop- 
per is   entirely  different. 
In  place  of  the  breakers 
on    the    regular    feed 
grinder,  this  hopper  has 
a  bottom  that  is  incUned 
toward   the   grinding 
plates.    This    bottom  is 
securely  riveted   to  the 
sides  of  the  hopper  and 
directs  the  grain  into  a 
worm  feed  which  forces 
it  into  the  grinding  plates. 

Where  a  mill  iswant- 
ed  that  will  grind  small 
grain  in  large  quantities, 
this  mill  will  be  found 
eminently  desirable.  The 
speed  at  which  this  mill 
is  run  and  the  amount  of 
power  used  determines 
its  capacity.  Each  horse 
power  will  develop  175 
revolutions  per  minute 
and  the  mill  should  be 
run  at  a  speed  of  from 
800  to  1,500  revolutions 
per  minute. 

A  very  superior  feat- 
ure of  this  feed  mill  is  its 
adjustable  shut-off.  By  means  of  this  shut-off,  the  feed  may  be  closed  down  or  regulated 
so  that  it  can  be  operated  with  as  low  as  4-horse  power.  The  amount  of  grain,  the  horse 
power  used,  and  the  speed,  determine  the  capacity.  Of  ordinary  small  grain,  this  mill 
will  grind  from  1 0  to  50  bushels  per  hour.  With  1 ,200  revolutions  per  minute  and  a  6-horse  power 
engine  25  to  35  bushels  of  oats  per  hour  can  be  ground.    This  mill  does  not  require  a  fly-wheel.

Worm  Feed 


The  International  Small  Grain  Grinder  has  a  worm 
feed  which  forces  the  grain  into  the  grinding  plates  very 
rapidly.  The  speed  may  range  anywhere  from  800  to  1,500 
revolutions  per  minute.  To  grind  a  large  quantity  of  grain, 
it  is  essential  that  this  mill  be  operated  at  a  high  rate 
of  speed.  The  worm  feed  is  a  great  advantage  and  is 
a  very  efficient  factor  in  regulating  the  amount  of  grain 
going  into  the  grinders,  thus  preventing  over-loading. 

In  the  illustration  on  this  page  the  hopper  and 
grinding  plates  are  removed  from  the  mill  to  show  the 
construction  of  this  worm  feed. 


Rate  of  Feed 


The  amount  of  grain  which  is  fed  into  the  grinding 
plates  is  regulated  by  an  adjustable  shut-off  located  in  the 
hopper  just  over  the  worm  feed.  This  shut-off  is  so 
arranged  that  the  mill  can  be  operated  not  only  with  a 
4-horse  power  engine,  but  equally  well  with  an  8  or  10- 
horse  power  engine. 

The  shut-off,  which  has  proved  itself  in  every  way 
satisfactory,  has  been  no  small  aid  in  making  the  Inter- 
national small  grain  grinder  popular.

Both  running  and 
stationary  grinding  plates 
on  the  Type  C  feed  grind- 
er are  alike.  Three  dif- 
ferent styles  of  plates  can 
be  used  in  this  grinder — 
coarse,  medium,  and 
fine.

Hopper 


The  hopper  is  strongly  made  of 
sheet  steel  and  is  thoroughly  reinforced 
at  the  top,  the  outer  rim  being  turned 
completely  over  around  an  iron  rod 
This  construction  prevents  the  hopper 
from  being  bent  or  damaged  as  is 
frequently  the  case.  This  hopper  is 
constructed  with  a  bottom  which 
inclines  toward  the  opening  just  above 
the    worm  feed.    The    inside    of  the

hopper  is  perfectly  smooth  and  there 
are  no  projections  to  obstruct  the  grain. 
The  shut- off  shown  in  the  two  accom- 
panying illustrations  is  a  very  desirable 
feature  of  this  grinder  as  it  permits 
only  the  desired  amount  of  grain  to  be 
fed  into  the  grinding  plates.  It  can  be 
adjusted  according  to  the  amount  of 
power.  When  this  shut-off  is  closed, 
no  grain  can  get  into  the  grinding 
plates.

Ground  i't-ed  Not  Only  Makes    Fine  Beef  but  Also  Increases  the  Milk  YiL^ld 

Advantages  of  Ground  Feed 

Prof.  W.  J  Kennedy  of  the  Iowa  State  College,  in  an  article  in  the  Farmer's  Tribune  on 
the  subject  of  grinding  feed  for  live  stock,  says: 

"A  careful  study  of  the  experiments  conducted  by  the  various  experiment  stations 
under  a  variety  of  conditions  and  with  different  classes  of  stock,  has  invariably  shown  that  it 
requires  less  ground  grain  to  produce  a  given  amount  of  milk,  meat,  or  work  than  it  does  when 
whole  or  unground  grain  is  used.  In  some  instances  the  difference  is  very  wide— as  high  as 
35  per  cent  being  saved  by  grinding,  while  in  other  instances  the  difference  is  not  very  marked. 
Averaging  up  the  results  of  all  the  tests  reported,  we  find  that  there  is  a  saving  of  about  12 
per  cent  effected  by  grinding  feed  for  the  various  classes  of  animals. 

"  The  above  calculations  are  based  on  simply  the  cost  of  grinding  and  the  feed  saved 
by  doing  so.  They  do  not  take  into  consideration  the  influence  which  ground  feed  may  have 
on  the  animal.  In  some  instances  where  animals  are  out  of  condition  or  are  teething,  it  may 
be  almost  necessary  to  feed  ground  feed  regardless  of  the  price  of  feed  stuffs  or  of  grinding  the 
grain.  Cases  of  this  kind  must  always  be  considered.  So  far  we  have  treated  the  matter  in 
a  general  way.  We  will  now  discuss  it  in  a  different  way,  treating  each  of  the  various  classes 
of  stock  independently  of  the  others.  For  horses  at  real  hard  work,  and  especially  if  they  are 
worked  long  hours,  all  the  grain  should  be  ground  and  mixed  with  chopped  hay.  By  so  doing 
you  will  save  the  horse  a  lot  of  time  and  energy,  both  of  which  are  important  considerations 
in  the  case  of  the  hard-worked  horse.  Old  horses  with  poor  teeth  should  always  be  fed  on 
ground  grain,  as  it  is  impossible  for  them  to  make  good  use  of  whole  grain.  Colts,  during  the 
spring  months,  or  at  any  other  season  of  the  year  when  they  are  shedding  their  teeth,  should 
have  ground  grain,  so  as  to  prevent  any  unnecessary  use  of  the  jaws  during  such  a  period.

Ground  Feed  Produces  Fine  Pork

"When  it  comes  to  the  cattle-feeding  business,  several  factors  must  be  considered.  The 
grinding  of  grain  is  generally  done  for  the  purpose  of  aiding  digestion,  thus  causing  less  waste 
of  the  grain  fed.  Where  hogs  are  used  as  followers  in  the  cattle-feeding  business,  there  is  not 
much  chance  for  waste  in  this  connection.  What  the  cattle  fail  to  utilize,  the  hogs  clean  up, 
so  that  the  two  together  make  a  very  good  combination.  These  methods  of  feeding  became 
almost  a  universal  practice  during  the  times  of  low-priced  feed  stuffs  and  scarcity  of  labor. 
In  those  days  everything  was  done  with  but  one  object  in  view,  which  was  to  save  labor. 
Corn  was  scooped  into  feed  troughs  and  the  animals  ate  what  they  wanted,  and  the  rest  was 
thrown  out  to  be  eaten  by  the  hogs  or  tramped  in  the  mud,  depending  on  the  condition  of  the 
feed  lot. 

"Things  have  changed  during  the  past  few  years.  When  feed  stuffs  are  high  in  price 
and  hogs  are  not  available  to  follow  the  cattle,  all  feed  should  be  ground.  For  a  quick  finish 
and  good  results  in  the  feed  lot,  the  following  method  of  feeding  is  quite  often  adopted,  and 
usually  with  good  results: 

"The  cattle  are  started  on  snap  corn,  on  which  they  are  fed  about  four  weeks.  They 
are  then  fed  on  shelled  corn,  crushed  corn,  or  corn  and  cob  meal  for  about  six  weeks.  From 
this  time  on  they  are  fed  on  corn  meal  and  some  supplementary  feed,  such  as  oil  meal,  gluten 
feed,  cottonseed  meal,  or  dried  blood.  Such  a  method  would  always  involve  the  grinding  of 
feed.  Corn  and  cob  meal  has  given  very  good  results,  and  in  feeding  experiments  has  given 
equally  as  good  results,  pound  for  pound,  as  corn  meal.  It  is  shown  that  corn  and  cob  meal 
gave  the  best  daily  gain  in  both  cases.  In  one  instance  less  corn  and  cob  meal  was  required 
for  a  given  gain,  while  in  the  other,  more  was  required.  The  average  of  the  two  trials  shows 
that  a  pound  of  corn  and  cob  meal  is  equal  to  a  pound  of  pure  corn  meal  in  steer  feeding.  In 
explanation  of  the  marked  difference  in  the  amount  of  feed  required  for  a  given  gain  in  two 
trials,  we  have  the  following  statement  concerning  the  cattle:  'The  first  lot  of  steers  were  a 
thin,  half-grown  lot  of  "natives,"  while  the  second  lot  were  high-grade  short-horns,  mature  and 
full-fleshed  at  the  start.'      The  second  lot  was  also  fed  for  a  longer  period.

"For  dairy  cows  giving  a  large  flow  of  milit,  all  kinds  of  grain  should 
be  ground.     Corn  and  cob  meal,  when  fed  with  oil  meal  or  gluten  feed,  is  pre- 
ferable to  corn  meal.    Corn  and  cob  meal  is  a  more  bulky  food  than  corn 
msal,  thus  better  adapted  to  the  needs  of  the  cow  from  a  digestive  standpoint.  Animals  under 
one  year  of  age  can  make  as  good  use  of  whole  fe.ain  as  they  can  of  ground  feed,  thus  there  is 
no  need  of  going  to  the  expense  and  trouble  of  grinding  feed  for  them.    Breeding  stock  usually 
makes  better  use  of  corn  and  other  grain  when  ground,  except  in  the  case  of  corn  when  it  is 
fed  in  the  snapped  form. 

"A  large  number  of  experiments  have  been  conducted  for  the  purpose  of  determining 
the  value  of  grinding  grain  for  swine,  and  on  averaging  all  the  results  it  has  been  found  that 
the  grinding  of  the  various  kinds  of  grain  effects  a  saving  of  about  eight  per  cent  of  the  grain 
fed." 

Experiments  that  have  been  conducted  prove  and  authorities  agree  that  cows  give 
more  milk  and  horses  are  capable  of  more  work  when  their  feed  is  ground;  cattle,  hogs  and 
sheep  can  be  fattened  more  rapidly  with  ground  feed  than  with  whole  grain.  Feeding  whole 
grain  is  very  expensive,  and  it  is  a  profitable  investment  to  have  a  feed  grinder  on  the 
farm  where  it  is  ready  for  use  when  desired. 


It  Pays  to  Grind  Corn  Cobs 

The  following  is  an  analysis  of  corn  and  cobs  under  the  signature  of  H.   E.  Wiley, 
United  States  Agricultural  Chemist,  at  Washington,  D.  C. 

Cobs  Kernels 

Water 9-33  per  cent  10.49  per  cent 

Ash 1-33  per  cent  1.55  per  cent 

Oil 47  per  cent  5.49  per  cent 

Carbohydrates 56.01  per  cent  67.72  per  cent 

Crude  Fibre 30.36  per  cent  2.13  per  cent 

Albuminoids 2.50  per  cent  10.62  per  cent 

The  analysis  shows  that  corn  cobs  are  of  value,  and  should  be  utilized  in  connection 
with  the  kernels  grown  upon  them.

Ever  Ready  Power 


I  H  C  Horizontal  Gasoline  Engine 
4,  6.  8,  10,  12,  15,  20  and  25-Horse  Power 


The  gasoline  engine  is  the  real  prac- 
tical power  producer  on  the  modern  farm. 

Gasoline  power  can  be  applied  not  only 

in  the  field  but  also  to  the  smaller  jobs 

around  the  house,  tool  house,  and  barn. 

It  will  furnish  convenient  power  for  op- 
erating the  feed  grinder,  and  is  especially 

adaptable  for  this  purpose  on  account  of 

the  variation  in  the  power  required  in 

proportion  to   the   kind   of    grain  being 

ground.      No  matter  how  much  power 

the  feed   grinder   needs   to  do  its   work 

properly,  the  I  H  C  gasoline  engine  will 

easily  handle  the  grain — and  at  so  small 

an  expense  that  the  amount  will  hardly  be  noticed. 

The  engine  can  be  started  simply  by  closing  the  switch,  opening  the  fuel  valve,  and  giving 

the  fly  wheel  a  turn  or  two.    A  child  can  start  it,  but  it  does  not  even  require  a  child  to  watch 

it  when  once  started.  It 
works  steadily  until  the 
fuel  is  gone. 

The  I   H  C  Line 
Includes 

I  H  C  Vertical  engines — 
made  in  2,  3,  25,  and  35- 

horse  power. 

Horizontal  (Portable  and 
Stationary)  in  4,  6,  8,  10, 
12,  15,  20,  and  25-horse 
power. 

Famous  air  cooled  en- 
gines—  in  1,  2,  and  3- 
horse  power. 

I  H  C  Gasoline  tractors 
in    various    styles    and 

sizes.
